The Dynect Platform for Managed DNS

• Managed Rock-Solid DNS• Global IP Anycast network• Active Failover: (disaster

recovery)• Load Balancing: (weighted,

round robin)• Global Routing: (regional

rulesets, real-time)• CDN Control: (costs, testing,

diversity)

This is not a Sales Pitch…Full- Disclosure & Transparency:

• Managed Providers: Neustar UltraDNS, Akamai, Verisign

Your Infrastructure & Why You Should Pay Attention to DNS

Load balance between your existing infrastructure and the cloud using DNS. We call it Dynect Traffic Management.

Dynect Traffic Management (DTM) – Take

Control

• Managed Global Server Load Balancing (GSLB)

• DNS based, as a service– No hardware– No CAPEX

• Distribute load to datacenters or availability zones in cloud environments

• DTM works in conjunction with existing local load balancers and health monitoring systems

Monitoring and Failover

• DTM can perform health checks against content servers and load balancers to see if traffic should be sent to that node

• Monitoring intervals – 1 minute

• Checks are performed from multiple datacenters to reduce false-positives

• HTTP and HTTP (with response inspection), SMTP, and ICMP checks available

Overcoming Browser

Limitations

• Recursive DNS servers, OSes, and browsers cache data: use extremely low TTLs and ensure fast delivery with anycast

• High performance managed DNS (Dynect Platform) easily handles low TTLs

Load Balancing Options

• Externally measured availability

• Externally measured latency– Real Time Traffic

Management

• Externally exposed internal metrics– Database load

• Internal decisions– Internal monitoring, internal

logic, Dynect API calls

Best Practice for Availability

& Performance

• Multiple geographic regions

• Each with a local load balancer– Enables rapid local failover

for isolated, local incidents • Server crash, disk failure

• Global Server Load Balancing via Dynect Traffic Management– Manage traffic to

geographic regions– Enables rapid global

failover for systemic incidents

• Upstream transit, power
